An on/off valve (O/OV) and directional valves (DV 1 , DV 2 ) are packaged with a switching valve system ( 10 ) in a housing assembly ( 156, 157, 158, 160 ). The on/off valve (O/OV) is operated by a control handle ( 154 ) that is located at one end of the housing assembly ( 156, 157, 158, 160 ). The direction control valves (DV 1 , DV 2 ) are operated by a handle ( 141 ) located at the opposite end of the housing assembly ( 156, 157, 158, 160 ). The control handles ( 154, 141 ) operate to position cams ( 152, 136, 138 ) which function to help position valve plugs. In a second embodiment, the handle ( 141 ) and cams ( 136, 138 ) for controlling the directional valves (DV 1 , DV 2 ) are replaced by a solenoid valve system (SV 2 ). A second solenoid valve (SV 1 ) is added to the control system for the off/on valve (O/OV). The solenoid valve (SV 1 , SV 2 ) allow for a remote positioning of the controls for the off/on and directional valves (O/OV, DV 1 , DV 2 ). The handles and cams ( 141, 154, 136, 138, 152 ) provide for a compact positioning of the controls at one location requiring utilization of a single compact valve housing assembly ( 156, 157, 158, 160 ).

Abstract

An on/off valve (O/OV) and directional valves (DV 1 , DV 2 ) are packaged with a switching valve system ( 10 ) in a housing assembly ( 156, 157, 158, 160 ). The on/off valve (O/OV) is operated by a control handle ( 154 ) that is located at one end of the housing assembly ( 156, 157, 158, 160 ). The direction control valves (DV 1 , DV 2 ) are operated by a handle ( 141 ) located at the opposite end of the housing assembly ( 156, 157, 158, 160 ). The control handles ( 154, 141 ) operate to position cams ( 152, 136, 138 ) which function to help position valve plugs. In a second embodiment, the handle ( 141 ) and cams ( 136, 138 ) for controlling the directional valves (DV 1 , DV 2 ) are replaced by a solenoid valve system (SV 2 ). A second solenoid valve (SV 1 ) is added to the control system for the off/on valve (O/OV). The solenoid valve (SV 1 , SV 2 ) allow for a remote positioning of the controls for the off/on and directional valves (O/OV, DV 1 , DV 2 ). The handles and cams ( 141, 154, 136, 138, 152 ) provide for a compact positioning of the controls at one location requiring utilization of a single compact valve housing assembly ( 156, 157, 158, 160 ).
